Typical for variable torque loads. The following Altivar technical documents are available on the Schneider Electric website www. Installation Manual This manual describes how to install and connect the drive. Programming manual This manual describes the functions and parameters of the drive's terminals and how to use them.
Quick Start The speed controller must be installed and set up conforming to the user manual and in accordance with both inte. Rejoindre Breizhbook. Bienvenue dans Breizhbook Connectez-vous Or sign in with:. The options also aid in troubleshooting in the event of a fault by displaying the fault code.
The PC connection option allows parameter settings to be saved on a diskette or hard disk for downloading into other drives. The difference is in the ability of the force-ventilated motor to supply torque below half speed without danger of motor overheating. Caution: consult motor manufacturer before operating motor above rated speed. When motor power is slightly higher than drive rated power, insure that the motor current is not higher than the continuous drive output current. In this case, it is necessary to provide separate overload protection by thermal sensor or relay.
If there are three or more motors in parallel, installation of a three-phase inductor between the drive controller and the motor is recommended. Altivar 16 AC Drive Drive controllers for asynchronous motors from 1 to 5 hp Drives with frequency range from 0. Applications: machines with high inertia, overhauling loads and machines with fast cycles. Actual power rating is W. Slip compensation is disabled when the motor is regenerating.
For demanding applications overhauling loads, hoisting it is necessary to calculate the value of the resistor. Consult your local sales office. The kit does not include an enclosure. Inductors Inductors protect against input line overvoltage and reduce the current absorbed by the drive. When used between the drive and the motor, inductors limit ground leakage interference currents.
To mount remotely, order kit VW3A also. A switch on the back allows selection of the adjustment mode or operation mode indicated by the LED. In the operation mode, adjustment of parameters is not possible, only display of electrical quantities, fault codes and parameter values. The software gives the following advantages: - Prepare a job in the design office without connecting the drive to the computer - Save configurations and adjustments on floppy or hard disk and download them into the drive - Provide a printout of documents for future reference The software allows access to all the adjustments of the VW3A display options as well as the supplementary functions of the option card.
It also allows the reassignment of the inputs and outputs of the option cards. Note: with the VW3A option, the specific control functions take priority over local control.
Applications All constant and variable torque applications with or without overspeeding. FrS: 40 to , preset to 50 or 60 using switch on the Altivar Adjustment of FrS overrides selection made with switch. Applications All applications. Applications All applications, from machines with fast cycles and low inertia to high inertia applications. Adjustments FLG: 0 to 99, preset to 33 From 33 to 0: reduction of gain machine with high resistive torque or high inertia From 33 to increase of gain machine with fast cycles and low inertia Code nFL: no frequency loop Example 1 Example 2 I N t t Instability of motor current In each case, reduce the gain.
Overspeed during a transient phase Slip compensation Function Maintain a constant speed to the motor for a given reference as the load changes, automatically correcting the frequency. Applications All applications which require a broad speed range with wide variations in resistive torque. Adjustment SLP: yes or no, preset to yes. T With slip compensation Slip compensation must be inhibited in the following cases: - High inertia machines - Synchronous reluctance motor - Variable torque applications pumps and fans T2 T1 f With the VW3A option, adjustment is possible from 0 to 5 Hz.
This function prevents the possibility of tripping due to an overbraking fault. Applications All applications not requiring a controlled stop on the deceleration ramp. Adjustment N 1 2 brA: yes or no, preset to yes. Motor thermal overload protection Function Indirect protection of the motor by continuously calculating I2t.
Adjustments t 10 mn ItH : 0. Adjust to the motor nameplate full load current. Switching frequency Function A high switching frequency allows the drive to supply the motor with a current waveform with low harmonics. The switching frequency is modulated to reduce noise generated by the motor. Applications Applications: Pumps, fans, or constant torque applications requiring a low level of motor noise at low speed. Applications Machines for which the speed is controlled by an external parameter.
Analog input AI Function Speed regulation with feedback by tachogenerator. Customer must provide an external resistor network to divide the voltage for adaptation of the drive to the tachogenerator voltage. Note: The drive insures that the input supply and the tachogenerator are galvanically isolated.
Analog input AI Function Simple regulation of flow or pressure or other process variable. Applications Pumps and fans. Function Switching to a second acceleration and deceleration ramp time, individually adjustable. Applications Material handling applications which require smooth starting and stopping. High speed spindles with acceleration and deceleration limits above certain speeds.

Torque regulation or simple tension-controlled applications. Use with a motor that has a power less than that of the drive. Logic inputs LI1 and LI2. Function Increase and decrease speed by using two logic inputs, with or without storing last reference similar to a motorized potentiometer.
Applications Command for a multi-drive system. Function Jog function with a minimum ramp of 0. Minimum time betweeen two jog pulses is 0. Applications Machines which run in manual. Used to move slightly forward when performing maintenance. Applications Conveyors with electric brake optimization of the braking time depending on the load.
Function Motor coasts to a stop. Motor and load deceleration time depends on motor speed, machine inertia and resistive torque. Applications Stopping with a mechanical brake or for positioning.
